AUTOMATIC PRESSURE-ROLL RELEASE FOR CLOTHES-WRINGERS.

Specification of Letters Patent.

Application filed October 26, 1916. Serial No. 127,901.

To all whom it may concern:

Be it known that I, REA P. WRIGHT, a citizen of the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Automatic Pressure-Roll Releases for Clothes-Wringers, of which the following is a specification, reference being had therein to the accompanying drawing. This invention relates to certain new and useful unprovements in a pressure roll release for clothes wringers, the object being to provide means for automatically releasing the pressure on the pressure rolls by providing the frame of the wringer with movably mounted pressure screw carrying boxes normally held in predetermined position by pivoted retaining members mounted on the top bar of the frame which are moved out of the path of travel of the boxes by pivoted levers carried by the side bars which are actuated by the separation of the pressure rolls.

Another object of my invention is to pro- Vide an automatic pressure roll release which is exceedingly simple and cheap in construction, the parts being so arranged that they can be readily installed on an ordinary wringer.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claims.

Inthe drawings,

Figure 1 is a side elevation partly in section of a wringer showing the application of my improved construction of release thereto; V

Fig. 2 is a detail top plan view of a portion of the wringer showing the retaining mec lnber in position within the sliding box; an

Fig. 3 is an end elevation of a wringer showing the lever for operating the retaining member.

Like numerals of reference refer to like parts in the several figures of the drawing.

In carrying out my invention, I'employ a wringer composed of a frame 1 having slotted side bars 2 in which are mounted superposed pressure rolls 3 and 4 provided with shafts 5 and 6 mounted in suitable bearings arranged within the slotted side bars 2 of the frame, the upper bearings being provided with spring supports 7 carrying pressure springs 8 which are engaged Patented Mar. 20, 1917.

by bearing plates 9 carried by a pressure bar 10.

Fixed within the slotted ends of the side bars 2 of the wringer frame, is a top bar 11 which is provided with a vertical bore adjacent each end in which a bearing sleeve 12 is secured which is provided with oppositely disposed grooves adapted to receive the oppositely disposed ribs of the internally threaded box 13 which is slidably mounted within the bearing 12 and is provided with a lug 14 extending into a slot 15 formed in the bearing 12 for limiting the upward movement of the box within the bearing. Mounted within. the threaded boxes 13 are pressure screws 16 adapted to engage the bearing plates 9 of the pressure bar 10 for adjusting the pressure on the pressure rolls 3 and 4 through the medium of the pressure springs 8.

The upper ends of the threaded boxes 13 are adapted to be normally held flush with the upper edge of the bearing 12 by pivoted retaining members 17 which extend over the upper edge so as to prevent the boxes from moving upwardly when the pressure screws are adjusted, said retaining members having portions 18 extending outwardly beyond the side bars2 of the wringer frame 1 in the path of travel of angled'levers 19 which are pivotally mounted on studs 20, carried by, the sidebars 2, the lower ends of said lever extending across the slots of the side bars above the upper pressure roll carrying shaft 6 and normally held a slight distance above the same so that when said shaft is moved vertically by the separation of the pressure rolls 3 and 4:, the levers 19 will be rocked on their pivots so as to bring the upper end portions into engagement with the outwardly projecting portions 18 of the retaining members 17. As the levers are swung on the pivot by the upward movement of the pressure rolls, the retaining members 17 are moved off of the upper edges of the boxes 13 so as to allow said boxes to move vertically within the bearings of the top bar in order to release the pressure on the pressure rolls.

From the foregoing description it will be seen that I have provided an automatic pressure roll release for a clothes wringer in which a bearing and slidably mounted pressure screw carrying boxes are mounted in the frame and retained in predetermined position by retaining members which are actuated by pivoted levers on'the separation of the pressure rolls so as to release the boxes.

I claim:

1. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, slidably mounted boxes mounted in said frame carrying pressure screws for adjusting said pressure means, retaining members pivotally mounted on said frame for holding said boxes in predetermined position, and levers mounted on said frame actuated by the separation of said rolls for moving said retaining members out of the path of travel of said boxes to release said pressure means.

2. A clothes wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, said frame having a top bar carrying bearing sleeves, internally threaded boxes slidably mounted in said bearing sleeves, retaining members pivotally mounted On said top bar adapted to extend over said boxes for holding said boxes in position within said bearing sleeves, and pivoted levers mounted on the side bars of said frame for moving said releasing members out of the path of travel of said boxes on the separation of the pressure rolls.

3. A clothes wringer comprising a frame v having pressure rolls and pressure means for said rolls mounted therein, a movable member having means for adjusting said pressure means, a pivoted retaining member for holding said movable member in predetermined position, a pivoted lever mounted on the frame of the Wringer and adapted to be operated on the separation of said pressure rolls, said pivoted member being arranged in the path of travel of said lever and actuated thereby on the separation of said pressure rolls for releasing said pressuremeans.

4. A clothes Wringer, comprising a frame having pressure rolls and pressure means for said rolls mounted therein, a top bar fixed in said frame carrying movably mounted boxes, pressure screws mounted in said boxes for adjusting said pressure means, pivoted retaining members mounted on said top bar for holding said boxes within said top bar, said retaining members having portions extending outwardly beyond the side bars of said frame, angular levers mounted on the side bars of said frame for moving said retaining members out of the path of travel of said boxes, said angular levers having portions arranged in the path of travel of one of said pressure rollshafts on the separation of said rolls.

5. A clothes wringer, comprising a frame having pressure rollsand pressure means for said rolls mounted therein, a top bar fixed in said frame, non-rotatable internally threaded boxes carried by said top bar having means for limiting the upward movement thereof, pressure screws carried by said boxes for adjusting said pressure means, pivoted retaining means mounted on said top bar arranged in the path of travel of said boxes, pivoted levers mounted on the side bars of said frame having portions arranged in the path of travel of one of the pressure roll shafts on the separation of said rolls for swinging said levers on their pivots, said retaining members having portions arranged in the path oftravel of said levers and adapted to be engaged thereby for moving said retaining members out of the path of travel of said boxes for releasing said pressure means.

In testimony whereof I hereunto affix my signature.
